How Fixed Deposit Rates Work in Singapore: Interest, Tenures, and Returns
Last reviewed: August 2026
Fixed deposits can provide predictable interest when money is set aside for an agreed period, but the headline percentage does not tell the whole story.
Fixed deposit rate Singapore financial institutions offer is usually quoted per annum, while the return also depends on the amount placed, the length of the placement, and the conditions attached to it.
Investors can review DBS’s current SGD fixed deposit rates alongside the available tenures and applicable terms before deciding where to place their funds.
Quick Summary
- A fixed deposit interest rate is usually quoted per annum, so the actual interest earned depends on the amount placed and how long the funds remain deposited.
- The fixed deposit tenure, applicable balance tier, and maturity instructions can influence the return and when the money becomes available again.
- Early withdrawal may reduce the expected interest, while eligible SGD fixed deposits are covered with other eligible SGD deposits up to S$100,000 per depositor per Scheme member under Singapore’s Deposit Insurance Scheme.
How Annualised Interest Applies to Your Deposit
A fixed deposit sets an agreed interest rate for money placed with a bank for a specified term. The quoted p.a. interest rate is annualised, so the actual interest credited depends on how much is placed and how long the funds remain on deposit.
Unlike an ordinary savings account, the money is committed for a defined period, which can make fixed deposit returns easier to estimate in advance. Traditional fixed deposits also differ from structured deposits, where returns may depend on the performance of an underlying asset or benchmark.
According to MoneySense, interest on a traditional fixed deposit remains fixed through the term if there is no early withdrawal, while structured deposit returns can vary with market-linked conditions.
What to Consider Beyond the Advertised Fixed Deposit Rate
A higher advertised rate can increase potential interest, but it should not be assessed in isolation. MoneySense notes that “Fixed deposit rates and features vary across banks,” so anyone comparing a fixed deposit rate in Singapore should also check the tenure, minimum placement, maturity options, and withdrawal conditions.
| Factor | What to check | Why it matters |
| Annual rate | Quoted % p.a. | Sets the basis for interest calculations |
| Tenure | Length of placement | Determines how long funds are committed |
| Deposit amount | Minimum and applicable balance tier | May affect the available rate |
| Liquidity | Early withdrawal terms | Accessing funds early may reduce returns |
| Maturity instruction | Withdraw or renew | Determines what happens when the term ends |
Protection is another separate consideration. Eligible SGD deposits are covered under Singapore’s Deposit Insurance Scheme, while foreign currency deposits and structured deposits are excluded from that protection.
This distinction helps investors evaluate not only potential fixed deposit returns, but also access to funds, product conditions, and the level of protection attached to the deposit.
How the Interest Calculation Works
1. Start with the quoted annual percentage
The percentage shown by a bank is only the starting point for estimating what a placement may earn. A p.a. interest rate expresses interest on an annual basis, so the amount received depends on the principal and the fraction of a year that the funds remain deposited.
For a simple estimate, investors can use: estimated interest = principal × annual rate × placement period as a fraction of one year. The bank’s own calculation method and account terms determine the final amount credited.
2. Check the length of the placement
A shorter or longer placement can carry a different rate, which means the fixed deposit tenure should be checked alongside the advertised percentage. DBS currently accepts new Singapore-dollar placements for periods of up to 12 months, while rates for periods of 18 months and above apply only to rollovers of existing placements at the same length.
3. See whether the balance changes the applicable rate
The applicable rate can also depend on how much money is already held in the account. For DBS, rates on new placements and renewals are calculated using the total SGD fixed deposit balance rather than assessing each placement separately, so an additional placement may move the account into another balance tier.
4. Decide what happens when the placement ends
Before confirming a placement, investors should also decide what should happen when the agreed period ends. DBS allows customers to renew principal and interest, withdraw both amounts, or renew the principal while withdrawing the interest, and these placement options can affect when money becomes available for other needs.
Sample Calculations for Six- and Twelve-Month Placements
Using an illustrative rate of 1.50% p.a., the examples below show how placement length affects the estimated interest on the same S$10,000 principal.
| Tenure | Principal | Illustrative rate | Calculation | Estimated interest |
| 6 months | S$10,000 | 1.50% p.a. | S$10,000 × 1.50% × 6/12 | S$75 |
| 12 months | S$10,000 | 1.50% p.a. | S$10,000 × 1.50% × 12/12 | S$150 |
Illustrative calculations only. Actual interest depends on the bank’s applicable calculation method and terms.
Early withdrawal
If the funds are needed before the agreed end date, the expected return may be reduced. DBS states that premature withdrawal can result in lower or no interest, and a fee may apply, so investors should review the early withdrawal conditions before committing money.
Common Myths About Rates, Returns, and Protection
Myth #1: Once a bank publishes a rate, it stays available.
Reality: A published rate reflects the terms available at a particular point in time rather than a permanent offer. DBS states, “Rates quoted are in % p.a. and are subject to change without prior notice.” Investors should therefore verify the current rate and applicable conditions immediately before placing or renewing funds.
Myth #2: The longest placement always earns the highest return.
Reality: Rates can differ across tenures, and a longer commitment does not automatically produce a higher annual percentage. The appropriate fixed deposit tenure depends on both the available rate and when the funds may be needed.
Myth #3: A 2% annual rate means a six-month placement earns 2% of the principal.
Reality: An annualised percentage must be adjusted for the actual placement period when estimating interest.
Myth #4: Every separate deposit receives S$100,000 of protection.
Reality: Eligible SGD deposits are aggregated up to S$100,000 per depositor per Scheme member under Singapore’s Deposit Insurance Scheme.
Frequently Asked Questions
How is the interest amount estimated?
For a straightforward placement, estimated interest reflects the principal, quoted annual rate, and time the money remains deposited. A shorter term therefore earns only the corresponding portion of the annualised rate.
Does a higher rate automatically mean a better choice?
Not necessarily. A higher fixed deposit interest rate should still be weighed against the commitment period, placement amount, access to funds, and applicable conditions.
Can I take out the money before the agreed end date?
Banks may allow early access, but the outcome depends on their terms. With DBS, withdrawing early can result in lower or no interest, and a fee may apply.
Are these deposits protected in Singapore?
Eligible SGD fixed deposits are covered with other eligible SGD deposits under the Deposit Insurance Scheme, up to S$100,000 per depositor per Scheme member.
Why should I check the latest published terms?
Rates and product conditions can change. Checking the latest published terms before placing funds helps ensure that the decision is based on current information.
Check the Latest Fixed Deposit Rate in Singapore Options Before Placing Funds
Choosing a fixed deposit involves more than comparing headline percentages, particularly when different tenures, balance tiers, and withdrawal conditions can affect the outcome. Matching the placement period to your cash needs can help you assess potential returns without compromising access to money you may need sooner.
Before committing funds, review the latest Singapore-dollar fixed deposit rates from DBS alongside the applicable terms and placement requirements.
